Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a platform for installing and dismantling cantilevered components. Background Technology

[0002] Cantilever components, especially cantilevered I-beams, are a type of structure in which one end is fixed to the main structure and the other end is free to be set. They can resist overturning and bending moments through the fixed point and are widely used in construction, cantilever walkways and other fields.

[0003] Cantilevered components typically involve high-altitude operations. In particular, when disassembling and assembling multiple and continuous cantilevered components, it is usually necessary to erect a large number of scaffolds below or to move the construction platform on the cantilevered components by manually carrying them back and forth. However, the method of erecting scaffolds is costly, and both existing methods have the problems of low construction efficiency and high safety risks. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings mentioned above by providing a cantilever component installation and dismantling platform that reduces investment costs while improving construction efficiency and safety.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a cantilever component installation and dismantling platform, comprising a load-bearing component, a limiting component, a constraint component, and a driving unit; The load-bearing component includes a first platform plate and a second platform plate that is slidably disposed on one side thereof; The limiting component includes two limiting assemblies respectively disposed on each platform plate; The limiting component includes two limiting plates symmetrically pivotally connected to the corresponding platform plate, and each limiting plate is used to engage with the cantilever component to fix the corresponding platform. The constraint components are mounted on each platform plate and are detachably connected to each of the limiting plates to constrain the rotation of each of the limiting plates; The drive unit is located between the two platform plates and is used to drive each platform plate to move forward alternately.

[0006] Furthermore, the limiting plate is composed of a transmission section rotatably disposed on one side of the corresponding platform plate and a limiting section connected thereto, and the limiting section is provided with a limiting groove corresponding to the cross section of the cantilever component.

[0007] Furthermore, the limiting plate is provided with multiple limiting holes; The constraint component includes a constraint assembly disposed on each platform plate and corresponding to each of the limiting plates. The constraint assembly consists of two constraint plates and a pin respectively disposed on both sides of the limiting plate. Each of the constraint plates is also provided with a through hole corresponding to the limiting hole, and the pin passes through each of the through holes and the corresponding limiting hole to constrain the rotation of the limiting plate.

[0008] Furthermore, one of the constraint plates in each constraint component is provided with a snap-fit; The pin consists of an insertion section that passes through each of the through holes and the corresponding limiting holes, and a constraint section that is vertically arranged thereon. The constraint section engages with the buckle to constrain the movement of the insertion section.

[0009] Furthermore, a first U-shaped groove is formed on the first platform plate; The drive unit is disposed in the first U-shaped groove, and its telescopic end is connected to the first U-shaped groove; The second platform plate has an inverted second U-shaped groove, the groove wall of the second U-shaped groove is slidably connected to the groove wall of the first U-shaped groove and connected to the fixed end of the drive unit.

[0010] Furthermore, each platform is also equipped with protective components, including protective railings surrounding each platform and operating levers set on the working end of the first platform.

[0011] Furthermore, the protective railing consists of protective side railings respectively installed on the side of each platform away from the drive unit, and gate railings respectively rotatably installed on each of the protective side railings. The gate railings are detachably connected to each other to facilitate the entry and exit of personnel from the platform.

[0012] Furthermore, the second platform plate is equipped with a hoisting component, which consists of a guide frame, a winding rod, and a hoisting rope; The guide frame guides the displacement of the hoisting rope, and the winding rod is used to wind up and unwind the hoisting rope to lift the cantilevered component.

[0013] The beneficial effects of this invention are reflected in: This invention uses a drive unit to move each platform plate sequentially on a continuous cantilevered structure, allowing the platform plates to change location according to the construction site. This eliminates the need for scaffolding and manual handling, reducing costs and improving construction efficiency. During the movement of each platform plate, workers can use corresponding limit plates to restrain the corresponding platform plate on the cantilevered structure, preventing accidental movement and ensuring the stability of the work platform, thus improving construction safety.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-6 The present invention discloses a cantilever component installation and dismantling platform, including a load-bearing component 1, a limiting component 2, a restraining component 3, and a driving unit 4; The supporting component 1 includes a first platform plate 11 and a second platform plate 12 slidably disposed on one side thereof, each platform plate being used to support workers and provide construction space; The limiting component 2 includes two limiting assemblies respectively disposed on each platform plate; The limiting assembly includes two limiting plates 21 that are symmetrically pivotally connected to the same side of the corresponding platform plate. Each limiting plate 21 is separably snapped onto the cantilever member 01 to limit the movement of the corresponding platform plate. The constraint component 3 is installed on each platform plate and can be detachably connected to each limiting plate 21 to constrain the rotation of each limiting plate 21; The drive unit 4 is located between the two platform plates and is used to drive each platform plate to move forward alternately.

[0018] In practice, when it is necessary to disassemble and assemble the continuous cantilevered component 01, the worker separates the limiting plate 21 on the first platform plate 11 from the cantilevered component 01. Then, the driving unit 4 drives the first platform plate 11 to move towards the next cantilevered component 01 until it reaches the predetermined position. The worker then engages the limiting plate 21 on the first platform plate 11 with the corresponding cantilevered component 01 to constrain its movement. Then, the worker separates the limiting plate 21 on the second platform plate 12 from the cantilevered component 01 and drives it to move with the driving unit 4 until it is flush with the first platform plate 11, thereby enabling each platform plate to move on the cantilevered component 01.

[0019] This invention uses a drive unit 4 to move each platform plate sequentially on a continuous cantilevered component 01, so that the position of each platform plate can change with the construction site. This eliminates the need for scaffolding and manual handling, reducing costs and improving construction efficiency. During the movement of each platform plate, workers can use corresponding limit plates 21 to restrain the corresponding platform plate on the cantilevered component 01 to prevent accidental movement, thus ensuring the stability of the work platform and improving construction safety.

[0020] Preferably, the drive component can be a double-acting hydraulic cylinder as in the prior art.

[0021] In one embodiment, the limiting plate 21 is composed of a transmission section 211 rotatably disposed on one side of the platform plate and a limiting section 212 connected thereto. The constraint member 3 is detachably connected to each limiting section 212, and the limiting section 212 is provided with a limiting groove 2121 corresponding to the cross section of the cantilever member 01. When each limiting section 212 rotates to a vertical state, each limiting groove 2121 can engage with the side wall of the corresponding cantilever member 01. When the limiting grooves 2121 on the two limiting sections 212 on the platform plate are relatively locked onto the corresponding cantilever member 01, each limiting plate 21 cooperates to prevent the platform plate from moving along its length direction.

[0022] With this design, when the corresponding platform plate moves to the predetermined position, the staff can rotate the two limiting plates 21 on the platform plate to a vertical position, so that the limiting grooves 2121 on the two limiting segments 212 are set relative to each other and locked on the corresponding cantilever component 01. Then, the limiting components 3 are used to constrain the movement of each limiting segment 212, thereby constraining the platform plate to move along its length direction. When it is necessary to move the platform plate, the staff can release the constraint of the constraint component 3 on each limit segment 212 and rotate each limit plate 21 again to separate it from the corresponding cantilever component 01.

[0023] In one embodiment, the limiting plate 21 is provided with a plurality of limiting holes 213; The constraint component 3 includes a constraint assembly that is disposed on each platform plate and corresponds one-to-one with each limiting plate 21. The constraint assembly includes two constraint plates 31 disposed on both sides of the limiting plate 21. Each constraint plate 31 is also provided with a through hole 311 corresponding to the limiting hole 213. When the limiting plate 21 is rotated to a vertical or horizontal position, the corresponding limiting hole 213 on the limiting plate 21 is coaxially disposed with each through hole 311. It also includes pins 32 that pass through each through hole 311 and the corresponding limiting hole 213 to constrain the rotation of the limiting plate 21.

[0024] With this design, when the platform needs to be restrained from moving, the worker rotates the two limiting plates 21 to a vertical position. At this time, each restraining plate 31 contacts the side of the corresponding cantilever component 01, and the end of each limiting segment 212 located below the platform is engaged with the cantilever component 01. Meanwhile, the limiting hole 213 on the end of the limiting segment 212 located above the platform is coaxially set with the through hole 311 on each restraining plate 31. Then, the worker inserts the pins 32 into each through hole 311 and the corresponding limiting hole 213 in sequence to prevent the limiting plate 21 from rotating accidentally.

[0025] In one embodiment, one of the constraint plates 31 in each constraint component is provided with an L-shaped buckle 33; The pin 32 consists of a plug section 321 that rotatably passes through each through hole 311 and the corresponding limiting hole 213, and a constraint section 322 that is vertically arranged on it. When the constraint section 322 is engaged in the buckle 33, the buckle 33 can constrain the plug section 321 to rotate circumferentially through the constraint section 322, and at the same time, it can also constrain its axial movement.

[0026] With this design, when the corresponding limiting hole 213 on the limiting plate 21 is coaxial with the through hole 311 on each constraint plate 31, the worker inserts the plug section 321 into each hole and rotates the plug section 321 until the constraint section 322 is engaged in the buckle 33. Thus, the constraint section 322 constrains the circumferential rotation of the plug section 321 while constraining its axial movement, so as to prevent the pin 32 from accidentally falling off.

[0027] In one embodiment, a first U-shaped groove 111 is provided on the first platform plate 11, the drive unit 4 is disposed in the first U-shaped groove 111, and the telescopic end of the drive unit 4 is connected to the groove wall of the first U-shaped groove 111. The second platform plate 12 has an inverted second U-shaped groove 121. The groove wall of the second U-shaped groove 121 is slidably connected to the corresponding groove wall of the first U-shaped groove 111 and is connected to the fixed end of the drive unit 4.

[0028] With this design, the first U-shaped groove 111 provides an installation position for the drive unit 4, so as to avoid the drive unit 4 protruding from the working surface of the first platform plate 11 and interfering with the operator's work. The interlocking and sliding arrangement of the two U-shaped grooves ensures the connection between the two platform plates while keeping the working surfaces of the two platform plates always connected.

[0029] In one embodiment, each platform plate is further provided with a protective component 5, which includes a protective railing 51 surrounding each platform plate and an operating stop bar 52 provided on the working end of the first platform plate 11.

[0030] With this design, when workers are working, the guardrail 51 is used to prevent workers from accidentally falling off the platform, and when workers are disassembling or assembling the cantilevered component 01, the operating stop 52 is used to prevent workers from bending over excessively and accidentally losing their balance, thus ensuring work safety.

[0031] In one embodiment, the guardrail 51 consists of guardrails 511 respectively disposed on the side of each platform away from the drive unit 4, and door rails 512 respectively rotatably disposed on each guardrail 511. Each door rail 512 is detachably connected to each other to facilitate workers to enter and exit the platform.

[0032] In one embodiment, the second platform plate 12 is provided with a hoisting component 6, which includes a guide frame 61 and a winding rod 62 disposed on the second platform plate 12; The winding rod 62 has a lifting rope 63 that overlaps the guide frame 61. The lifting rope 63 is used to lift the cantilever component 01 to be disassembled. The guide frame 61 is used to guide the movement direction of the hoisting rope 63. The second platform plate 12 is also equipped with a power unit (not shown in the figure). The moving end of the power unit is connected to the winding rod 62 to drive its rotation.

[0033] With this design, when it is necessary to hoist the cantilever component 01, the staff connects the cantilever component 01 to be installed with the hoisting rope 63 and drives the winding rod 62 to rotate through the power unit to wind up the hoisting rope 63 until the hoisting rope 63 hoists the cantilever component 01 to the platform plate. When it is necessary to place the cantilevered component 01 for dismantling, the power unit drives the winding rod 62 to reverse so that the hoisting rope 63 can lower the cantilevered component 01, thereby improving construction efficiency.

[0034] Preferably, the power unit can be an electric motor from the prior art.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0037] Additionally, "multiple" refers to two or more.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
